Re: Y70-70 Touch Laptop (Lenovo) Screen flickering

Thank you for writing in to the Lenovo Forum - happy to have you here today.

To fix the flickering problem, you should first check the laptop cables for loose connections. So engineer have already diagnosed and confirmed, it was not the lcd cable which is faulty.

Another possible reason for the flickering problem in computer screens is interference of magnetic fields from other gadgets. Yes, check if near your laptop, you haven't placed speakers, fluorescent lights, cell phones, radios and any other electrical device. If it is so, you must remove any such interfering electrical gadgets away from your laptop. Studies have proved that cell phones do cause screen flickering.

Try and identify when you face this issue, when on Battery power, mains AC adapter or in both scenarios? Is it for a particular power plan or for all power plans? Also check if this happen when you enter BIOS and in Safe Mode too.

Please follow the below steps:

If updating video drivers does not help, uninstall and reinstall the Video drivers.

Open Control Panel\All Control Panel It ems\Power Options\Edit Plan Settings and restore the default power plan settings by clicking on Restore default settings for this plan. Do this for all your Power Plans.

Change the refresh rate and see if that helps.

Update us how it goes.

Re: Y70-70 Touch Laptop (Lenovo) Screen flickering

I checked and the screen doesn't flicker in Safe Mode neither in BIOS.

It happens in both situations - When the AC adapter is plugged and when its not.

It flickers on all power plans.

I thinks its not from magnetic fields because I removed all gadgets and the problem presisit.

I checked the cables plugged in the laptop and its not from them.

I followed all the steps but the problem presists.

I noticed that when I watch youtube videos it flickers more and when I try to play Flash Games in the browser the flickering is the most.Its nearly impossible to play Flash Games in the browser because of the flickering.

If the problem is caused from something that is inside the laptop and if I open it will it void the warranty of the laptop ?
